CAR-WH EEL.

SPECIFICATION forming part of Letters Patent No. 256,841, dated April25, 1882.

Application filed March 7, 18872. (No model.)

To all whom t may concern Be it known that l, THOMAS E.h KNAUss, ofNelsonvi'lle, in the county ot' Athens and State of Ohio, have inventedcertain new and useful Improvements in Gar-Wheel Hubs; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, which will enable others skilled in the art to whichY itappertains to make and use the same, reference being had to theaccompanying drawings, andto letters of reference marked thereon, whichform a part of this specification.

Figure 1 represents an end view of the nave 0r hub of the wheel,lookingfrom the outside. Fig. 2 represen ts a section taken on the broken linex. Figs. 3 and 4. represent detail views, showing the securing-plate.

This invention relates to improvements in ear-wheels of that class whichrevolve on their axles, more particularly to the construction of theirhubs for forming an oil-receptacle and means of securing the wheel onthe axle.

The invention consists in ahub having partitions of peculiarconstruction and supplyholes, and also in a lock-plate, all ashereinafter set forth and explained.

In the annexed drawings, the letter a indicates the nave or hub ot' awheel, having the bore or bearing b for the axle and the recess c forthe axle-collar. Running across thishub lengthwise of the bore orbearing b are several partitions, d, which divide the interior of thehub into as many chambers. The partitions d extend from the bearing bradially and up to the shell a of the hub. They may be cast in one piecewith the bearing and the shell or be separate and secured thereto. Ineither instance they extend from one to the other, as shown, bracing thewhole structure. These partitions may be made of two dimen sions orthicknesses, the outer one, e, bracing the hub of the wheel, and theinner one,j', which is thinner, serving to divide the hub, as described.The difference in the thickness of these partitions is shown in Fig. 2and the thinner portions by dotted lines in Fig. l; but tlfesepartitions may be made ofthe same thickness throughout, this not beingmaterial. In these partitions are cut passages g, of any suitable sizeand shape. These passages permit a complete iow around the hub, ashereinafter described. In each of the chambers of the hub, between thepartitions, apertures h are made in the box i, leading into the bore l).These apertures have a are above and below, as shown, so that theirpassage-ways Z are smaller than their tops and bottoms. Thisconstruction forms an excellent oil-cham ber for the hub, for thepartitions force the lubricant against the hub and the passages g allowof a steady flow around it, thus inducing action at the apertures h, andthese by their peculiar shape conduct the lubricant to the bore and thenspread it on the journal.

At the outer end of one or more of the partitions d the hub a isprovided with an oset or ange, lr, extending` on both sides of thepartitions, and having the bevelm and straight face n.

The locking or axle-securing plate p is providedwith a bevel, q, to itthe under bevel, m, of offset Z, and bears against the face u. Thisplate has two lugs, o, one of which comes on each side of partition d,holding the plate firmly in position, while the inner notched end, s, tsin groove t at the end of the axle and holds the wheel on. In Fig. Ithis plate is shown in position by dotted lines. The plate is preventedfrom coming oft' by the cover-cap o, which is bolted to the hub, and hasan oil-hole, zo. Itl desired, more than one of these plates can beemployed.

This provides a simple and easy way of securing the wheel to the axle,keeping it firmly in place, and yet it can be quickly and readilyreleased.

Having described myinvention, what-Iclaim 1. A. car-wheel hub havingpartitions which extend lengthwise of the bearing and from the latter tothe shell, and are provided with passages for the lubricant, and alsohaving apertures between such partitions, all as set forth.

2. In a carwheel -hub provided with a lu bricating-chamber, theapertures h, having their passage-way Z smaller than their tops andbottoms, as set forth.

3. The hub having the offset and partitions, in combination with theplate having the lugs and the notch, andthe axle having the groove, allas set forth.

In testimony that I claim the foregoing as my own I aflix my signaturein presence of two witnesses. 1
